| Abstract: | In this paper, we have investigated Bianchi type-III cosmological model in the presence of a bulk viscous fluid together with
zero-rest-mass scalar field and time-dependent cosmological term. We have shown that the field equations are solvable for
any arbitrary cosmic scale function. Exact solutions of Einstein’s field equations are obtained which represent an expanding,
shearing, non-rotating and decelerating model of the universe. Some physical and geometrical behaviours of the cosmological
model are discussed. |
